AI Scientist, Finance (Mistral Science) - Paris
Paris · Full-time
Why join Mistral AI?
The prize is every government, bank and hospital that wants frontier AI without handing its data to someone else's cloud, and Mistral AI, a Paris open-weight AI lab, is positioned to supply it. If sovereign AI becomes a procurement rule, the company could end up inside many public institutions. A $3.5B Series D backed by NVIDIA and Bpifrance, with $7.5B raised across nine rounds, puts real money behind 212 open roles.
JustBacked's take, based on Mistral AI's own site and its funding and hiring data.
